This research was conducted to achieve several objectives and focus research was based on financial behavior theory and prospect theory as grounded theory e.g., investigate the financial decision-making behavior between financial and real assets investment, and confirm the relationship existing between herding behavior and overconfidence factors to the level of loss and regret aversion, and financial literacy into real assets investment decisions. The study used 220 real estate auction respondents as investor samples at the State Assets and Auction Service Office Makassar, South Sulawesi, Indonesia. Data was collected through the use of a questionnaire consisting of 23 questions to measure the variables. Moreover, the research data passed through several feasibility tests like the inner and outer modeling by Partial Least Square-Structural equation model (PLS-SEM) while the hypotheses formulated were also tested to determine the magnitude of the variable relationship. Through the use of the direct and intervening test, loss and regret aversion variables have a positive and significant effect while financial literacy variables have no significant effect. There is a slight difference in the decision-making process for real assets and financial assets investors. Investment decision making behavior in the financial assets sector requires less complicated decisions compared to the decisions related to real assets investments.

Carbon emission disclosure serves to justify firms' sustainable business endeavors. This study contributes to the minor discussions of this topic in the context of Indonesian. The role of media exposure to moderate the firms' size, profitability, leverage, and environmental performance toward carbon emission uses is also inadequately addressed in previous studies. This study aims to fill these discrepancies by investigating financial statement data of firms listed in the Jakarta Islamic Index, Indonesia (JII), from 2012 to 2016, employing moderated regression techniques. All direct relationships are significant. The media exposure significantly moderates firms' size and leverage, but not to profitability and environmental performance. We also discuss several considerations with environmental disclosure issues in Islamic Index along with its implications.

The purpose of this study is to determine the impact and consumptive behavior of students from an Islamic economic perspective.

Purpose: This study aims to analyze the effect of service quality on loyalty mediated by customer satisfaction and trust. A total of 215 Islamic bank customers in the study area were sampled accidently.   Theoretical framework: Theoretically, this study contributes to the gaps in the literature, especially those related to the effect of SQ on Islamic banking loyalty which is mediated by satisfaction and trust simultaneously in one research title. Practically, encouraging Islamic banking management to design SQ programs that integrate the value of satisfaction and trust in the same cultural background to gain customer support and loyalty   Design/methodology/approach: There are four latent variables observed; service quality, satisfaction, trust, and loyalty with the number of indicators respectively six, four, three, and four. Data collection was carried out through interviews using a questionnaire. Data were analyzed using Smart-PLS 3.0. The validity test uses factor loading and AVE ( Average Variance Extracted ), the reliability test uses Composite reliability (CR) and Cronbach's Alpha (CA), the direct effect test uses the path analysis matrix, while the indirect effect test uses the specific indirect effects matrix.   Findings: The volume of research has been increasing over the past nineteen years, although there are only a few authors, institutions and reference journals contributing to the topic’s consolidation and the countries conducting the most joint research in co- authoring for the largest volume of publications, authors and impact journals.   Research, Practical & Social implications: This study concludes that customer loyalty of Islamic banks in Indonesia can be optimized through service quality which is mediated by customer satisfaction and trust.   Originality/value: The results of the analysis show that the factor loading value is> 0.6 and the AVE value is> 0.5 which means that the data is valid. CR and CA values > 0.6 which means the data is reliable. The direct effect test shows that service quality, satisfaction and trust have a positive and significant effect (p-value <0.05) on loyalty. Furthermore, service quality has an indirect effect ( specific indirect effects) on customer loyalty through the mediation of satisfaction and trust.
